ICL7662CBA+T

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7662CBA+T is a charge pump voltage converter manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface-mount package. It operates with an input voltage range of 4.5 V to 20 V and provides a single output interface capable of delivering up to 20 mA. The device functions as an inverting DC/DC converter, generating a negative output voltage relative to the input. It features a switching frequency of 10 kHz and supports a maximum output power of 500 mW. The component is designed for operation within a temperature range of 0°C to 70°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the SOIC-8 footprint matches the target PCB layout dimensions. Validate that the 4.5 V minimum input requirement aligns with the system power rail specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple inverting topology is required for low-current applications. Consider the 20 mA output current limit against the load requirements. Evaluate the 10 kHz switching frequency for potential noise sensitivity in adjacent analog circuitry. Compare physical size constraints of the SOIC-8 package against available board space.
